Toiall' 'whom 1Itmay concern; y

Be it kriovvnthat I, JOHN E. OsMER,'a citizen Iof the United states,residing at' Chicago, in the County of (look and `State. otfIllinois,lhave invented certain new and useful 'Improvements in VCombination.Wheeland-'ihre Gages, oi which the following isa specification.

l Thisinventionrelates more particularly to gages or 'devices adapted tobefused for determining various measurements, defects' or necessarychanges to be .made in connection with railway car, locomotive or otherflanged wheels. lts objects are to produce an accurate and convenientmeasuringy instrument for 4Il'leainring or determining a number ofmeasurements or esta vin connection with the rims and flanges of suchWheels.

It is illustrated in the accompanyingdrawingsfin proved gage shown asappliedA to 'a worn lrim and Bange fordetermining certain measurements;Fig. 2 represents a reverse side ofthe gage, showing additionalgraduations and lines for making other ,1neas urements; arid Fig. 3 isalso a view of the reverse side,

showing its application to awheel fordetermining the` .1.' 25:

extent of chipped rims. i

As illustrated in these'drawings, this gage is shown with ,scales Yandindicating-,marks corresponding in the; ma'in'with the present rules ofthe Master Car Builders? Association of the United States; but, ofcourse, this device may befprovided with any desired dle-portion Ahaving a hook-like extension B` which,

for convenience, will 'be called a "hook7 One of the necessarymeasurements to be determined-in connection-with anged wheels is thethick- -ness of the flange, 4which, .for convenience, is determined at apoint 17/64 of an inch above the tread of the-.wheeL Her'etofore noinstrument has been provided for accuiatelydetermining this measurement.

'By me'ans ofjmr improved gage, this measurement may be accuratelydetermined as shown in Fig. l.

The handle-portion A is provided with a slide 'O bottom ofthe groove inwhich the slide is secured Vand This slide is prothe gage. Now, when thegage is adjusted to the 'wheel so that the lower edge a rests on theVtread oi the wheel and the hookB is brought into engagement with theface of the wheel, lthen the thickness of the flange may be determinedby moving the slidel C .out until the point c engages with the flange.-This will give the exact thickness, and in order to determine' thethickness I have provided a scale E onfthe body of the gage along theupper edge of the slot for the slide C.

An indicatingline c on the slide indicatesthe desired `thickness of theflange. For instance, as shown in Fig. l, the flange measures l. inch inthickness which is below the standard required for railway wheels.

To do so, the rim'must necessarily be turned 'off for a sufcient depthin order to secureenough. stock to shown on the body of the gage at Fjust below the slot 'for the slide, and are so arranged that, when theslide is moved to determine the thickness oi the fiange, the indicatingline c will also indicate the cut to be taken on the tread of the wheel.As shown in the drawing,

4the thickness of the flange being'indicated as l inch,

the necessary cut to be taken to restore the fiange to its propercondition is indicated at the bottom of the slide as 12/32 andthe dottedline indicates where this measurement `is to betaken and also indicatesthe new tread of the wheel after it has been turned to the proper shape.This figure also indicates another measurement which thev gage isadapted to determine. When the tread'becomes grooved, leaving a secondflange or raise as indicated at y, it is also necessary to restore thewheel to -proper condition. The extreme depth of such groove before theWheel is condemned has been fixed at of an inch. Accordingly, I haveprovided an indicating mark a, as shown at the righthand end of the gagefor determining this measurement. lt will be observed that the scales Eand F might, in someinstances, be placed on the slide Land indicatingmarks or pointers made on the body of the gage, and

such scales might be changed in full according to the nature of thewheels or flanges which are to be Ineasured. As shown in Fig. 2,theopposite or reverse side of the gage is provided with a scale G which isadapted to measure the height of the vertical wear of the tire flange,and also for showing the height of the flange. This is clearly indicatedas the gage is shown in con- AThis standard y'requires that the flangeat this point ing flat spots on the trend of the riin, or for making anyother measurements for which it would be convenient. The reverse side isalso provided iriili'nn indicating line J for determining the soie orunsiil'e condition nl' a broken Wheel tread. i

The position oi' the gage, in connociion with :i chipped rim, is shownin Fig. 3. According to the `accepted standards, if the chipping doesnot extend past the lineJ or is only on the side of the line marked O.1L, then the Wheel would be considered soie. However, ii the chipextends beyond tiro line to the sido marked 13.0., then the Wheel wouldbe vconsidered in bud order and Would be condemned. v L Having thusdescribedrny invention, what I claim and desire to secure by LettersPatent is: v

L 'llie combination with i gage adapted to fit on the rim of a wheelland provided with a hook to engage with the face of the wheel, of asliduble indicating member forl measuring the thickness of the iiange ata given distance from the race oreille wheel.`
